GASOLINE RE SERVE .GAUGE'.

Application filedSeptemher 21, 1925.

The object of my inven-tionis-to provide a gauge which willat all timesindicate the amount of gasoline remaining in the fuel supply tank, andwhich will automatically closethe outlet supply pipe when-the gasolineis lowered toa certain designated level within the supply tank;

Another object is to provide special regulating valve that willautomatically close the-valve ports when the gasoline level. reaches acertain point, and may also be operatedto release the remaining supplyof zig asoline from the supply tank, if so desired by: the operator.

A further object is to provide an automatic gasoline reserve gauge thatis simple iirconstruction easily: and etliciently oper. ated and: can beniianufactured at a low cost.

These several objectsare attained by'the construction and arrangement ofparts more fully hereinafter set forth.

Similar parts on all drawings are marked by similar numerals.

T will now describe more fully the detailed construction of my; device,referring; to the drawings and the marks thereon.

The general construction of my device comprises-a glass gauge tubeconnected directly to the bottomof a gasoline supply tank by m'eans ot'aspecialoperating valve and connectingpipe,- so arranged as to posi-Serial N0? 57,565.

Theglass gauge tube-is graduated to indicate the amount of gasoline in thetanlo A special valve'connectingg-th'e'bottomof the gauge tube with thetank, is provided with an automatic float valve; operating in such" amanner as to close the port in the valve when the gasoline in the supplytanlereafch'es a certain designated level I therein, thus giving theoperator warnin'giof the low fuel supplybea tore same becomes completelyexhausted. On turning rthe valve to another posit-loin a ditiieren't setof ports again connect the supply tank with the-outlet port and theremaining gasoline can be then drawn there tl'roi'n. v manner andpurpose as toproducethesame effect as aspe'cial reserve gasoline tankbuilt therein.

The glass gauge tubelis connected to the gasoline tank -2 by means of a8 tliree-wayrvalve 3 and pipe 4:-, the gauge "being positionedapproximately at the same level as tank 2-. Thevalve 3- having.- theport connectingr nipples -5+, 6- and -7 positioned in the 8 same'planeand project-inggfrom the casing; -3- atright angles'to the axis of thetapered valve p lug -8. The glass tube -1 being opened at "each end isprm ided with I end"caps 9 and l0-, which are recessed to tittightly-thereon and provided wi h i packing gasket -11- for making thejoints air tight; The two end caps *9 mid -1d being-firmly heldin placeby the threaded tie rods l2-- passing; and engagingthe'projectingflangesot the caps. The botton'i'cap,l0 %isprovided with a threaded openingt13through the center thereof for receiving the threaded nipple 5 of theoperating valve 3--, forming a direct passage between the gaiige andvalve 3. The-valve port nipple is connected directly-with the gasolinesuppl fitank --2- by the pipe The port nipple -7- leads: to the enginecarburetor; Through the center of the valve casing -8- is fitted thetapered valve plung- 8-, tree to turn therein and firmly held' inpl-acebyia coil spring; 14- j' mounted on the outer end 'of the valve plugand:held in plac-e "by.

The special valve operating in a 7 ill;

the washer and pin -16. The rotation of the plug 8- within the casing -3is regulated by a projecting boss stop -17 on the side of the casting,which engages a stop pin -18 projecting from the side of the valve plug8, limiting the movement of the plug 8- to an open and closed positionrelative to the gauge port 13 Through the center of the valve plug 8-,and at right angles to the axis thereof, is placed a passage tube 19,and connecting the ports in the nipples 5 and 7- and forming a straightchannel through the valve, when in the open position as indicated inFig. 1, and also in detail in Fig. 4:. Through the side wall of thevalve plug 8', and in line with the port nipples 5, 6 and -7, is formedan external grooved passage -20, of a width slightly greater than thepassage tube 19 which passes through the plug 8., and extends across theface of the plug sufficiently to include both ports of the nipples 5 and6-, as shown in Fig. i of the drawings, allowing a free gasoline passagefrom the tank 2 directly into the gauge tube 1, thence down through theplug tube -19 and out of the port in the outlet nipple 7, to the enginecarburetor. lVithin the glass gauge tube 1 is placed a small float 21which will rise as the gasoline rises within the tube when filling thegasoline supply tank 2. The float 21- carries a suspended valve pin -22-having ball valve 28 attached to the bottom end thereof. The valve pin22 being of a sufficient length to project the ball 7 end -23 within thenipple port 5 and engage the top end of the plug tube 19- when thegasoline level approaches a low level in the gauge tube --1 and tank 2-,closing the port through the valve plug and preventing further flow ofgasoline there from, leaving a reserve supply of gasoline within thesupply tank 2, giving warning to the operator of the low supply of fuel.The length of the valve pin --22 determines the amount of gasoline leftin the supply tank 2 at the time of the closing the valve port -19. Uponthe valve ball -23 closing the valve port, thus giving warning of lowgasoline supply, the valve plug 8 may then be turned within the casing3, to its lower position as indicated in Fig. 5, so that the groovedpassage 20- engages and incloses the ports in the nipples -6 and 7,forming a direct passage way through the valve leading from the tank 2to the carburetor of the engine, the ball valve 23 being supported onthe smooth face of the valve plug 8-. The glass gauge -1- is graduatedas indicated in Fig. 1, toshow the amount of gasoline within the supplytank --2, and the topcap 9 provided with a small hole 24 to allow foradjustment of air pressure as the level of gasoline is varied therein.
